IPC: H01B13/00
Filed: 1987-03-27
Abstract: PURPOSE:To make a long-size oxide series superconductor continuously manufacturable in an efficient manner, by extruding slurry of the oxided series superconductor and a non-superconductive mineral with a die, setting it down to a complex line, and after heating and driving this complex line, carrying out a degressive process, then winding a metal tape on the outer circumference while carrying out a twisting process. CONSTITUTION:Slurries 1 and 2 of an oxide series superconductor and a non- superconductive mineral are set up so as to cause the non-superconductive mineral to surround the oxide series superconductor, and these slurries 1 and 2 are extruded by dead load of these slurries 1 and 2 or pressurization with a die 5, setting it down to a complex line 6. And, after this complex line is heated and dried up, a degressive process is carried out, then a metal tape 10 is wound on the outer circumference while performing a twisting process. With this constitution, a long-size line of the oxide series superconductive wire being in a low magnetic field and showing stable and excellent characteristics is seasily manufacturable.

Title: Preparation of vibration proof rubber
Inventor: SONODA MASAAKI
IPC: B29D22/00
Filed: 1985-04-08
Abstract: PURPOSE:To make it possible to obtain arbitrary load characteristics, by performing the molding of rubber after a plate material was inserted between inner and outer cylinders and subsequently withdrawing the plate material to pertially form a hollow part in rubber. CONSTITUTION:A plate material 38 is attached to a mold in a non-adhesive state to be inserted between an inner cylinder 26 and an outer cylinder 28 and, at the same time, projections are inserted from the mold as cores in order to mold hollow parts 32, 36 and, thereafter, rubber is molded between the inner cylinder 26 and the outer cylinder 28. This molded rubber is adhered to the outer periphery of the inner cylinder 26 and the inner periphery of the outer cylinder 28 by vulcanization and the plate material 38 is withdrawn from the rubber 30 along with the cores in order to mold the hollow parts 32, 36. By this method, a hollow part 34 having a narrow width is formed in addition to the hollow part 32. In this vibration proof rubber, because the hollow part 34 is immediately closely contacted when the outer cylinder 8 receives load in the direction shown by an arrow A with respect to the inner cylinder 26 at the time of use, non-linear characteristics can be obtained almost only in a single side. If the wall thickness of the plate material 30 is altered if necessary as mentioned above, various load characteristics can be obtained.
